Looks like lots of rust? The cut out over the rear doors would be a deal breaker for me. Need more detailed pics of inside and underneath. No goodies, slider, and the Quigley setup will probably need $2 to 3k to RIP it and replace wear parts. May of may not be full floater rear axle.
You have a very low mileage 7.3, that is your strongest selling point.
Price? What are you asking?
